X 350d models are offered in conjunction with the high-level Power equipment line only, and features LED high-performance headlights with cleaning system; LED tail lights; electrically folding exterior mirrors; and keyless entry, all as standard.

Inside, the X 350d comes with electrically adjustable driver and front passenger seats, which are heated, along with a leather steering wheel with gearshift paddles and cruise control.

In 4MAT mode the vehicle automatically manages the force distribution. That way, if the vehicle registers loss of grip the torque is applied to the rear axle instead.

In the 4H (High Range) mode a low locking effect of the interaxle differential is presented. This leads to a reduction of the control intervention and therefore improved response characteristics.

The 4L mode (low range) is suited for driving on terrain where maximum force at low speeds is required, such as on steep slopes or muddy roads.

Using the Dynamic Select controller the driver can choose between five individually defined drive transmission modes (Eco, Comfort, Sport, Off-Road, and Manual) which allow the vehicle character to be adjusted as desired.
